Title: Rotation speed detector for fan motor
Inventor: KAWACHI NOBUYOSHI
IPC: H02P29/00
Filed: 1989-01-30
Abstract: PURPOSE:To protect a machine from breakdown by providing a circuit for detecting the rotation speed of a fan motor and producing a signal when the rotation speed drops below a predetermined level. CONSTITUTION:When a fan motor 1 for radiating heat from the interior of an electronic machine is rotating steadily, output rotary waveform of the motor 1 is applied onto terminal A of a monostable multivibrator IC2 thus producing a low level voltage V0 from terminal Q. When the rotation speed of the motor 1 drops to a predetermined level, the IC2 detects the drop in the rotation speed of the motor 1 to produce a high level voltage V0 from the terminal Q. By such arrangement, the electronic machine can be protected from breakdown due to inner temperature rise.

Title: Preparation of sintered ore
Inventor: SHIBUYA TEIJI
IPC: C22B1/16
Filed: 1984-02-08
Abstract: PURPOSE:To prevent the lowering in the quality of a sintered ore followed by the generation of gaps in the both side parts of a pallet caused by the sintering tightness of the sintered ore and the leakage of air used in sintering, by placing powdery limestone and powdery coke to both side parts of the pallet of a sintering machine at the time of the preparation of the sintered ore for a shaft furnace while placing the stock material for the sintered ore to the central part of said pallet. CONSTITUTION:In preparing a sintered ore for a shaft furnace in a DL type sintering machine, a sintering stock material hopper 6a storing a powdery iron ore is placed above the pallet 3 of the sintering machine and hoppers 6b for mixing powdery limestone and powdery coke are provided to both sides of said hopper 6a. These stock materials are supplied on the pallet 3 through a rotary feeder 7 and a sloping chute 8 and the sintered stock material 1 is placed to the central part of said pallet 3 while the mixture 4 consisting powdery limestone and powdery coke is placed to both sides thereof. Even if the sintering stock material 1 is sintered and shrunk by sintering tightening, powdery limestone is present between both side walls 3a of said pallet 3 in a state baked to quick lime by coke and gaps are not generated. Therefore, both side parts of the sintered ore are cooled by excessive sintering air and strength is not lowered. Further, quick lime baked in both side parts 4 can be utilized as the stock material of the sintered ore.

Title: Ion vacuum pump
Inventor: TORIKAI TOSHITAKA
IPC: H01J41/12
Filed: 1979-02-22
Abstract: PURPOSE: To improve attainable vacuum degree in high-vacuum region by making easier the starting-up of exhausting performance in the early period of start of exhaustion by providing an ion gun consisting of an electron filament and a rare gas ion accelerating plate at a rare gas inlet.  
     CONSTITUTION: In the early period of the start of exhaustion, a rare gas is introduced from the rare gas inlet 6, ionized by the electron filament 7, accelerated by the ion accelerating plate 8, and then thrown at the latticed cathodes 3 and 3'. The cathode material subjected to a sputtering by the impaction of rare gas is sent to the collectors 4 and 4' to form a clean film on the cathode material. The clean film can perform an exhausting action because of its chemical activity. In this case, the speed of exhaustion becomes higher than the redischarging speed of exhaust gas by a synergistic effect of the discharge mechanism between the cathodes 3 and 3' and the sputtering mechanism of the cathodes 3 and 3' of the ion guns 6 to 8, so that exhausting work can be attained in a faster time. Also, attainable vacuum degree can be improved by introducing a rare gas in the high-vacuum region for ionization.

Title: Photometric device of single-lens reflex camera
Inventor: HASEGAWA HIROSHI
IPC: G03B7/099
Filed: 1980-02-22
Abstract: PURPOSE:To reduce a trouble of adjustment and the cost by equalizing exposure information before photographing to an exposure control value in photographing, by equalizing the quantity of photodetection of a photodetector for exposure control in photographing to that in observation. CONSTITUTION:In observation, light from an object passes through photographic lens 3 and the 1st mirror 5 and is reflected by the 2nd mirror 6 to strike photodetector 2. In photographing, the light passed through photographic lens 3 is reflected by film 8 or shutter blind 7 with a reflection coefficient close to that of the film to strike photodetector 2. So that the quantity of photodetection of photodetector 2 in observation will be equal to that in photographing, transmission factors and reflection factors of photometric mirrors 5 and 6 are fixed. Consequently, exposure information before photographing becomes equal to an exposure control value in photographing and because only one photodetector 2 is in use, the trouble and cost are reduced. In addition, the exposure is determined by previously flashing the speed light device.

Filed: 1981-02-16
Abstract: PURPOSE:To have secure and well-separated feed of paper sheets in a copying machine etc. to the last sheet loaded, by such a construction that a longer guide plate is laid between the sheet loading means and sheet feeding roller, nearer the loaded sheets, so that the free end can attain the feed roll contact point or its adjacency. CONSTITUTION:Upper part 4a of a guide plate 4 is fixed to the guide plate mounting groove 18 provided at a part of the sheet loading means, where the free end 4b shall be so arranged as dangling to the contact point 10 of regular and reverse rollers 8, 9 or its adjacency. In this case, the length of the guide plate 4 is set larger than the distance between the mounting groove 18 and contact point 10. Accordingly, rotation of the regular rotating roller 8 will carry the free end 4b to the contact point or its adjacency, and the guide 14 covers the reverse roller 9. Thus the leading edge 19a of the last sheet 19 is moved in the direction of feeding securely by rotation of the regular roller 8, so that the reverse roller 9 does never affect the sheet with its reverse transporting effect. Thus the sheets can be fed securely to the last one.
